Overclocking

Starting out stock, we see the 9900K bouncing around between 4.3GHz and 5.0GHz as windows does its own internal tasks behind the scenes.

We want to try the new AI Overclock tool, so we’ll try it first.

We turn on the AI OC which gives us an all-core speed of 5.1GHz.

This gives us about 150 points more in Cinebench over stock.

Next, we’ll flip over to manual mode and try to get a little more.

We just couldn’t quite get 5.2GHz stable, even closely matching ASUS’s Ai prediction settings. If we hit it a little harder with voltage, the temps climbed over our self-imposed limit of ~90C. 5.1GHz on eight cores isn’t bad so.

We pushed the memory speed up to 3466 MHz with no changes to voltage or timings.

This gets us a tiny bit more score, about 30 points. But we feel this is a good everyday speed.
